Canon Background

Sarek is the Vulcan ambassador to Earth during the original series and has married Amanda Grayson, a human woman, ostensibly because "it seemed the logical thing to do." They have one child together, Spock. Fans have long speculated as to the true nature of their relationship, but the most recent film definitively states that it was a love match.

Sarek has a strained relationship with Spock; they were estranged following Spock's decision to join Starfleet, but even after their reconciliation in "Journey to Babel", their onscreen moments together look awkward (or just really Vulcan?).

Sarek dies in the TNG era of a Vulcan equivalent to Alzheimer's disease.
